Abstract

The present disclosure relates to the field of endovascular treatment. More particularly, the present invention uses a modified hydrogel intrasaccular occlusion device designed to implement an endovascular treatment to ameliorating or eliminating aneurysm recurrence, which hydrogel may optionally be impregnated with pharmaceutical compounds. The present invention also teaches the use of thin hydrogel coatings to ameliorate endovascular treatment related difficulties.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A device for ameliorating aneurysm recurrences by deploying amorphous hydrogel; said device further including:
 a treatment mesh,
 wherein said treatment mesh further includes at least one reinforcement element comprising a telescoping center-support bar, wherein said telescoping center-support bar further includes umbrella-like radial support struts; and 
 wherein said amorphous hydrogel is affixed to said telescoping center-support bar, and said umbrella-like radial support structures, 
 wherein said at least one reinforcement element minimizes risk of collapse. 
 
 
     
     
       2. The device of  claim 1 , wherein said amorphous hydrogel is impregnated with pharmaceutical compounds. 
     
     
       3. The device of  claim 1 , wherein said device comprises a thin coating of said amorphous hydrogel on any surface exposed to blood or a lumen wall. 
     
     
       4. A device for ameliorating vascular outpouchings by deploying amorphous hydrogel; said device further including:
 a treatment mesh,
 wherein said treatment mesh further includes at least one reinforcement element comprising a telescoping center-support bar, wherein said telescoping center-support bar further includes umbrella-like radial support struts; and 
 wherein said amorphous hydrogel is affixed to said telescoping center-support bar, and said umbrella-like radial support structures, 
 wherein said at least one reinforcement element minimizes risk of collapse. 
 
 
     
     
       5. The device of  claim 4 , wherein said amorphous hydrogel is impregnated with pharmaceutical compounds. 
     
     
       6. The device of  claim 4 , wherein said device comprises a thin coating of said amorphous hydrogel on any surface exposed to blood or a lumen wall.
